Effects of water quality on fish parasite biodiversity and physiological responses in the host fish Clarias gariepinus from a eutrophic lake subjected to acid mine drainage in South Africa

open access: yesIntegrated Environmental Assessment and Management, Volume 20, Issue 5, Page 1539-1553, September 2024.
Abstract Elevated concentrations of contaminants have negative impacts on aquatic organisms and their parasites. Changes in parasite infections have been proposed as a technique for monitoring the health of aquatic ecosystems. Furthermore, alterations in physiological responses (biomarkers) of organisms have also been used to delineate ecosystem ...

Using Bayesian multispecies models to evaluate fish and invertebrate detection probability and distribution in the hypersaline Bahia Grande tidal basin

open access: yesMarine and Coastal Fisheries, Volume 16, Issue 3, June 2024.
Abstract Objective In 2000, the Laguna Atascosa National Wildlife Refuge acquired the Bahia Grande (Texas) management unit, a space that had lain barren and arid for 70 years. A large cooperative partnership launched a restoration project to replenish the basin and recover its original tidal hydrology.

THE RELATIONSHIP BETWEEN DIET AND LARVAL DEVELOPMENT OF PALAEMONETES ,

open access: yesThe Biological Bulletin, 1957
1. Larvae of Palaemonetes pugio Holthuis and Palaemonetes vulgaris (Say) reared in the laboratory showed differences in survival, frequency of molting and rate of development which may be associated with the amount of food available.2. Larvae were unable to survive if fed diets of either single species or combinations of species of several unicellular ...

Evaluating impacts of environmental stress and bioactive chemicals on the North Carolina blue crab population: An individual‐based model

open access: yesMarine and Coastal Fisheries, Volume 16, Issue 2, April 2024.
Abstract Objective Recent estimates of the North Carolina blue crab Callinectes sapidus stock found that the stock is overfished and overfishing is occurring. Threats outlined in the 2018 stock assessment include climate change and estrogenic endocrine‐disrupting chemicals (EEDCs).

Evaluating uncertainty to improve a common monitoring method and guide management decisions for diamond‐backed terrapins

open access: yesThe Journal of Wildlife Management, Volume 88, Issue 1, January 2024.
Diamond‐backed terrapins are estuarine turtles threatened by bycatch mortality in crab pots. We found that a standard method for estimating terrapin survival has a low capacity to detect the true effect of bycatch reduction devices (BRDs) with 95% certainty.

Mechanisms That Generate Resource Pulses in a Fluctuating Wetland. [PDF]

open access: yesPLoS ONE, 2016
Animals living in patchy environments may depend on resource pulses to meet the high energetic demands of breeding. We developed two primary a priori hypotheses to examine relationships between three categories of wading bird prey biomass and covariates ...

Accumulation and Effect of Chromium on Protein and Glycogen Levels of Palaemonetes pugio [PDF]

open access: yesJournal of Animal and Veterinary Advances, 2012
Total metal accumulation and the levels of total protein and glycogen were measured in Palaemonetes pugio after exposing the animals to 0.05, 0.1 and 0.2 ppm concentrations of chromium over 1, 7 and 15 days. Metal accumulation in tisuues was measured using atomic absorbtion spectrophotometric techniques and the levels of total protein and glycogen were
